To all whom. it nuiy concern:

Be it known that 1, WILLIAM Form SCHMOELE, of Philadelphia,Pennsylvania, at present dwelling in Antwerp, Belgium, have invented thenew and useful Improvements in Motocyclos hereinafter set forth.

My invention, called a mote-monocycle, consists of a column composed ofa motor set upon a single ground wheel, and constitutes a steering orfore frame adaptable interchangeably to sundry non-motor drags orvehicles, to form atwill either (1) a motor bicycle, or (2) a motortricycle, this latter in many forms either for one persori or forseveral, as a buggy, hansom cab .or any other two-wheeled passengervehicle, or ior'goods and loads of all kinds, as a cart. Again (3) toform a motor launch when hung to the stern of any small boat, which itboth propels and steers; and finally (4) to constitute a stationarypower plant on a small scale. Its compactness and wide kinetic range (6powers) adapt it to all these uses, and it can be detached from any oneof the above functions, and harnessed up to another, as quickly and aseasily as a horse can be geared from one wagon to another, or to anotherservice.

Figure 1 represents my mote-monocycle, shown in full lines, attached toa single-wheel drag in dotted and dashed lines, forming thus a motorbicycle. Fig. 2 is a front view. Fig. 3 shows the same monocycle appliedto boat propelling and steering. Fig. 4 represents one of the collars inwhich it turns. Fig. 5 shows it geared to a hansom cab, with which itforms a tricycle. Instead of the cab, all kinds of two-wheeled vehiclescan be substituted, such as buggies and carts, &c.; even cannon andammunition caissons when the monocycle is made of larger size. Fig. 6shows it hung up on a wall or post, as a stationaryengine, for smallpower plants of all kinds. My moto monocycle consists of an explosionmotor a, set upon a velocipede forkc, which holds the ground wheel (1,preferably of a diameter smaller than usual in the fore-wheels ofbicycles, in order to lower the center of gravity when used for draft.Around the axle of this wheel is lodged a change-speed gear hereinaftercalled a speedalter, preferably constituted by a spur-wheel planetarytrain inclosed in an oil-tight box, and giving at least three speeds.-Any other kind of speedalter can be used if compact and snugly housablewithin and around the hub of the ground wheel.

Reverse-or backward motion is had without mech anisln byswinging thewhole monocycle around 180. The oil-tight box. containing thespeedalter, and represented in Fig. 1 by e, and in Fig. 2 bydottedlines, forms the hub of the ground wheel, and is held in the forkc. On itsperiphery several shells can be interchangeably fitted, each'shell carrying different outer Figs. 1 and 5, or to receive a belt, Fig.6; paddle blades for boat propulsion Fig. 3; or sprocket teeth toreceive a. chain, Fig. 6. 7 To double the number of powers obtainable bythe speedalter, it is made to undergo two rgimes by bringing the motivepower to it at diflerent speeds by means of chain or belt gears g h or gh Fig. 2, so proportioned preferably that one and the same chain or beltf will fit both pairs of gear interchangeably. Thus, for exam ple, thepower being brought in from the pulley g on the motor, to the pulley hon thespeedalter at a velocity double that by which it would enter ifthe belt or chain were transferred to the other set of pulleys g and h,a speedalter furnishing three speeds with the belt on g or h, say 4, 12and 16 miles an hour, would with the belt on g h furnish three otherspeeds, 8, 24 and 32 miles an hour. Thus my motomonocycle can do heavywork at slow speeds, or light work at high speeds. The motor may be ofthe ordinary 4 cycle type, and fired by hot-tube or byauto-incandescence. 'Better is a 2 cycle motor firedmagneto-electrically by a magnet contained in the twin fly-wheel 'u '1),which also acts as fan to the cylinder. To facilitate the steering, boththe motor, a, and the fuel tank y, as well as the other belongings,should be so located that their center of gravity may fall well behindthe pivot linet tFig.

1, whereby their weight will counterbalance that of the speedaltersituated ahead of this line. The carbureter and the muffler should bechosen of compact form, and, with all their accessories, should begrouped into the column, which thus forms a complete and selfcontainedwhole, to which any oneor two-wheeled drag may be hitched without anyother connection than the yokes or-collars 1. These, shown in detail inFig. 4 are simply two rings or circular-openings, forming part of theends of the frame q, which constitutes the bicycle drag Fig. 1, or isattached to the boat Fig. 3, or to the cab Fig. 5, or is sunk in thewall Fig. 6. These rings, preferably of a form, Fig. 4, to open by ahinge and to shut and lock by a bolt 'and nut, are at such distance fromeach other that one grasps the monocycle around its neck, just below thefuel; tank y and hand bars 2, the other around its waist, just below themotor a and above the fork c. Being free to turn in these collars, themonocycle can steer with ease, and can even turn 180 towards the sidewhere the belt or chain is not, thus producing reverse motion. But itcannot tilt nor fall sidewise without overturning the vehicle or boat,both too heavyto be upset by such a light weight. When fastened to awall, as in Fig. 6, the monocycle should be hindered turning,
